I've gravitated towards Maud's Coffee k cup variety pack (Coffee Lover's 40 count) from
Amazon. I preferred their flavoring in comparison to Brooklyn Blends variety count. When Costco has a good deal on their 72 count variety pack name brand k-cups (which I'm presently going through) I by that.
Great Value is actually pretty good so I've gotten that in the past. Presently we really only buy their Medium Roast Decaf which is quite good IMO.
We for almost 2 years bought from a local shop that does their own blends and purchasing of beans (and will grind the coffee based on your method of brewing) and doubles as a homemade chocolate shop however we paused that when we purchased from another local company (although much much larger) at Costco a special local blend because it was 2lbs worth but we'll go back to that other smaller local shop once in a while in the future, they have significantly raised their pricing (through no fault of their own, just pandemic-related transportation costs, etc) and it was hard to continue to pay $18-$20 for 12oz.
Oddly (or I guess it's that way for us) we recently found Whole Foods we found has a good espresso decaf blend and the slight Prime savings a nice feature.
We have 3 different coffee things: a Keurig, a pour over and newly an espresso machine (not an uber fancy one but not the extremely basic that barely qualifies as espresso).
I use the keurig during the week and while we have reusable filter I hardly use it and stick with k-cups.
We use the pour over with a finer grind for our weekends.
We use the espresso machine whenever we feel like it but largely with decaf beans (presently the bag from Whole Foods), since it's not used for our morning cup of coffee, that we use an electric grinder for.
I most prefer non-flavored and dark roasts. I don't mind some flavored coffee but find I just don't get that coffee flavor as much as one with just notes of flavors based on growing area and particular blends. My husband prefers light to medium blends. One thing we agree on is Starbucks is too bitter for us. I do find that variety packs allow for discovering what suits you and what brand suits you. I tend to try to stick around $0.50 or so or less per k-cup to keep costs in line when trying different companies.
